Original application filed May 20, 1922, Serial No. 562,462. "Divided and this application filed October My invention relates to feeding devices and is herein shown and described in conjunction with a newspaper stufling mach ne, such as shown and described in my copending application, Serial No. 562,462, filed May 20, 1922, of which the subject matter of this application is a division.

The invention has among its various objects the provision of a device capable of engaging and causing sheets or newspaper sections to be successively fed from a stack of sheets'or sections.

It is an object to provide a structure which will impart motion to the sheet to be extracted which motion will cause the sheet to be moved in one direction and removed from an abutment or support and then moved in the opposite direction to cause the sheet to be fed from the stack to other portions of the machine.

It is a further object to provide a support for the stack of sheets and to construct the support so that the means for feeding the sheets may be readily associated therewith.

In addition to the above it is an object to provide a construction which permits the parts of the feeder to be readily separated should this be found necessary for the purpose of making repairs or adjustments.

In addition it is an object to provide an arrangement which is simple and may be cheaply manufactured.

The invention will be explainedin detail and more readily understood when read in connection with the accompanying drawings which illustrate one embodiment of which the invention is susceptible, it being obvious that changes and modifications may be resorted to Without departing from the spirit of the appended claims forming a part hereof.

Serial No. 143,852.

Figs. 9 and 10 are respectively front and side elevations of a means for feeding the paper sections to the feeding device shown in Figs. 5 and 6; and

Fig. 11 is a front elevation of a portion, of the structure shown in Fig. 4.

The invention is herein shown and described in conjunction with a machine for feeding newspaper sections and causing one section to be inserted Within another and delivered as a unit from one end of the machine. The various devices for causing the several sections to be inserted are designated by the characters A, B, C, D, and E, each of which contains a pile of the various sections which are delivered to a delivery mechanism F. Thestructures of the various devices A to E being identical with each other the feeding device and other mechanism for operating the feeding device of one of said sections A to E will suffice for an understanding ofall.

The machine is designed to be actuated by a ter of which actuates a pinion-6. These latter pinions are respectively secured to shafts 7 and 8. The shaft 8 has a feed roller 9 secured thereto and the shaft 12 is provided with the roller 10 which is driven by a pinion 11 mounted on the shaft 12, the pinion and shaft being driven by a pinion 13 secured to said shaft 8. The shaft 14 uponwhich the gear 4 is mounted carries another gear 15 which meshes with the gear 16 provided upon the shaft 19. The shaft 17 is provided with another gear 20 which cooperates with, gear 21, the latter being secured to the shaft 22, all of which is clearly shown in Fig.2. The actuation of the gear 18 transmits motion to the rod 28 which is connected to a lever 24, one end of which is secured to the shaft 25.

This shaft has an arm 26 extending therefrom wards the carriage through the medium of the feedin mechanism 32, which in the present instance consists of a number of belts 33 traveling around pulleys designated 34 and 35. The means for causing an intermittent actuation of this feeding mechanism is clearly shown in Figs. 9 and 10, and includes an arm 36 secured to the shaft 25. A link the opposite ends of which are respectively secured to the arm 36 and to the arm 38, transmits the rocking motion of the shaft to the arm 38. The arm 38 is provided with a pawl 39 which cooperates with a ratchet 40 which it is evident will cause the belts 33 to be intermittently actuated upon each oscillation of the shaft 25, and will therefore feed the paper sections 31 toward the support 30. The news- 7 paper sections or sheets 31 rest upon abutments 41 which are secured to a bar 42 which supports said abutments. I p

The support 30 is provided with a plurality ofparallel grooves .32 and 44'which respectively receive extensions 45 and 46 of the respring pressed dogs, each of which is provided with needles which are designed to priclrinto the lowermost sheet or newspaper section to cause said sheet or section to be moved away.

from the abutment 41 and then moved in the opposite direction towards the rollers 9 and 10, and thence to other mechanism from which it is movedto the next device such as B. The

' dogs whereby the sheet or newspaper section is initially moved from the abutment 41 are designated 47 and are disposed on opposite sides of a centrally arranged rib 48'which is a part of the reciprocable carriage 29. These dogs are pivotally secured to a shaft 49 which extends transversely through the centrally arranged rib 48 and are provided with antifriction rollers 50, and are maintained in a position to engage the lowermost sheet or sec- 7 tion by means of, the expansion spring 51 which normally tends toj'move one end of these dogs towards said section. It is evident that when the carriage is moved in the direction of the arrow illustrated in Fig. 5, that the needles 52 of the dogs 47 will engage the lowermost sheet or section and move it in the direction" of the arrow and cause it to be released from theabutment 41. Upon the movement of the carriage29 in the direction of the arrow illustrated Fig. 6 the dogs designated 5353 will engage the lowermost sheet or newspaper section and move said section toward the feed rollers 9 and 10. These last mentioned dogs 5353 are actuatedtowards the newspaper sections or sheet by springs 54 and are also pivotally connected to the centrally arranged rib 48 of said carmit of this the carriage29 is recessedas at 57 which will allow the roller to be moved suiiiciently to permit the needle to be retracted fromthe sheet when the roller isengaged by the cam face 56, in which .position it will;

remain during the forward movement ofthe carriage in the cam track 55. Each ofthe dogs 47 and 53 includes a body generally designated 58. A removable block 59. and the needles which are interposed. between a portion of the body 58 and the removable block 59 are held in associated relation by a screw 60 which enters the body 58. The end of the body 58 and the corresponding end of block or bar 59 are correspondingly inclined to give needles 52 an inclination to facilitate grasping the paper sections, as shown in Fig. 5. Springs 59*, shown indottecl lines in Figs. 5 and 6 tend to force members 59 frombody 58. This structure is clearly shown in Fig. 8, from an inspection of'which it is evident that upon the removal. ofthe screw 60 the needles carried by said dogs may be changed or adjusted, depending upon any contingency which may arise. V y

In Fig. 11 a means is shown whereby the position of the carriage carrying the dogs may be varied with relation to other portions of the structure. This means includesr the arm 26 and an element 61 arranged v upon the shaft 25. This element 61 is provided with upwardly and laterally extending lugs 62 which are arranged upon opposite sides of a block 63 provided upon the arm 26. These lugs 62 respectively carry adjusting screws 64 and 65 which whenactuated will, through the medium of the movement of the arm 26, and the link 27 cause an adjustment of the carriage 29 which carries said dogs andthereby permit the carriage to be arranged in various positions relatively to other elements of the structure such as the rollers v9 and 10.

From the foregoing description it. is evident that a simple and effective structure is provided whereby a sheet or newspaper section" may be engaged and moved from an abutment or support and then moved from said position to anotherposition atwhich,

latter position the newspaper sheet or section may be fed to other instrumentalities of the device. It is further manifest that a means is provided whereby the dogs which cause the initial movement of the sheet or section are caused to be released from the newspaper sheet or section so that it may be moved'with respect to said dogs prior to the movement of the sheet towards said other instrumentalities of the machine, and will not cause any injury to occur to the sheet during these operations.

Having thus described my invention what I claim is:

1. In a machine of the class specified, the combination of a stack for holding paper sections and feeding mechanism for the same comprising sliding members carrying needles adapted to engage the lowermost paper section in the stack, said members being made with a detachable bar between which the needles may be detachably secured, said detachable bar having a slanting surface and the member carrying it having a correspondingly slanting surface, between which surfaces the needlesmay be detachably held.

2. Needle holding devices comprising separable members with needles interposed between them and means for drawing said members together, the cooperating ends of the separable members between which the needles are interposed being inclined to the means for drawing said members together, whereby said drawing means will exert a wedgelike or clamping action on the needles.

3. Needle holding devices comprising separable members with needlesinterposed between them and means for drawing said members together, a spring tending to separate said members.
